COMMUNICATION SYSTEM FOR VEHICLE AND ON-VEHICLE UNIT
PROBLEM TO BE SOLVED: To provide a communication system for a vehicle and an on-vehicle unit.SOLUTION: A communication system for a vehicle comprises an on-vehicle unit for periodically transmitting a signal from an antenna mounted on the vehicle, and a portable unit for receiving the signal transmitted by the on-vehicle unit and transmitting a response signal corresponding to a received signal. The system includes a rotation drive part connected to the on-vehicle unit for rotating the antenna by a control operation from the on-vehicle unit. The on-vehicle unit comprises: a detection part for detecting a getting-off action of an occupant riding in the vehicle; a position detection part for detecting a position of the portable unit in a time-sequential order based on the response signal from the portable unit; a determination part for determining a direction of movement of the portable unit after the getting-off action has been detected based on a change in the time-sequential positions of the portable unit; and a control part for controlling a movement of the rotation drive part so that the antenna faces a direction corresponding to the determined direction of movement.SELECTED DRAWING: Figure 5
【課題】車両用通信システム及び車載機の提供。【解決手段】車両に設けられたアンテナから定期的に信号を送信する車載機と、車載機から送信された信号を受信し、受信した信号に応じた応答信号を送信する携帯機とを備える車両用通信システムであって、車載機に接続されており、車載機からの制御により前記アンテナを回動させる回動駆動部を備え、車載機は、車両に乗車している乗員の降車動作を検知する検知部と、携帯機からの応答信号に基づいて、携帯機の位置を時系列的に検出する位置検出部と、携帯機の時系列的な位置の変化に基づき、降車動作を検知した後の前記携帯機の移動方向を特定する特定部と、特定した移動方向に応じた方向を前記アンテナが向くように、回動駆動部の動作を制御する制御部とを備える。【選択図】図５
